Comparison of Pre-Operative Endoscopic Retrograde Cholangiopancreatography Followed by Laparoscopic Cholecystectomy and Laparoscopic Cholecystectomy with Intraoperative Cholangiography in Acute Biliary Pancreatitis

Despite rapid economic growth during the last half of the twentieth century, gender inequality has remained high in Korea. Using data from the 2001 Korean National Health and Nutrition Examination Survey (KNHANES), previous research found that gender differences in sociostructural and psychosocial factors contributed to a substantial female excess in poor self-rated health. To the extent that women’s overall social status relative to men has improved over time in Korea, it is possible that the gender gap in perceived health has decreased. This study used repeated cross-sectional KNHANES data from 2001-2012 to examine temporal trends in gender differences in self-rated health. In age-adjusted models, we found no significant trend in the female excess of poor self-rated health among respondents aged 25-44 (p=0.685). In contrast, we found a statistically significant downward trend among those aged 45-64 (p<0.001). In fully adjusted models controlling for age and behavioral, sociostructural, and psychosocial covariates, we found a marginally significant upward trend (p=0.08) among younger respondents, while the downward trend among older respondents remained significant (p<0.001). More work is needed to determine why gendered health disparities decreased among older adults in Korea but not among those aged 25-44.
